Passenger Occupant Detection System
Passenger Occupant Detection System
Special tools, testers and auxiliary items required
• Pry Lever (80 - 200)
• Seat Repair Stand (VAS6136)
• Follow all safety precautions when working with pyrotechnic components. On the passenger occupant detection system, refer to => [ Passenger Occupant Detection Sensor Precautions ] Passenger Occupant Detection Sensor Precautions.
• Before handling pyrotechnic components (for example, disconnecting the connector), the person handling them must discharge static electricity. For example, by briefly touching the door striker pin.
The passenger occupant detection system service kit is precalibrated and must not be disconnected. The service kit consists of:
• Passenger Occupant Detection System Control Module (J706)
• Passenger Occupant Detection System Pressure Sensor (G452)
• Passenger Occupant Detection System Mat
• Seat cushion
• Wiring harness between the passenger occupant detection system control module -J706 and passenger occupant detection system pressure sensor -G452.
Removing
- Move the seat height to the middle position before removing the seat.
- Remove the front passenger seat:
• Manual standard seat, refer to => [ Manual Standard Front Seat ] Manual Standard Front Seat.
• Power standard seat and Comfort seat, refer to => [ Power Standard Front Seat ] Power Standard Front Seat.
- Disconnect the battery ground cable with the ignition switched on.
- Attach the front seat to the (VAS 6136). Refer to => [ Front Seat, Installing on Seat Repair Stand ] Overhaul.
- Remove the front seat backrest. Refer to => [ Front Seat Backrest ] Front Seat Backrest.
Do not disconnect the electrical connectors on the Passenger Occupant Detection System Pressure Sensor and the Passenger Occupant Detection System Control Module.
- Using a narrow screwdriver, carefully press the passenger occupant detection system pressure sensor - item 3 - off the bracket - arrow -.
- Open the seat occupied recognition pressure hose guide - 1 - and free up the pressure hose - 2 -.
- Remove the screw - 2 - and remove the passenger occupant detection system control module - 1 - from the retainer.
- Disconnect the safety belt latch connector from the bracket by pressing the release and removing the electrical connector.
- Free up the wiring harness.
- Remove the bolt - 1 -.
- Remove the front passenger seat position sensor (G554) - 2 -.
- Remove cover and cushion (seat pan without a seat height adjuster) from the seat pan and carefully fold it to the side. Refer to => [ Seat Pan Cover and Upholstery ] Seat Pan Cover and Upholstery.
- Carefully pry out the seat occupied recognition mat clips - 1 - and - 3 - on the front of the seat pan using a (80 - 200).
- Remove the seat pan cover and cushion by first guiding the passenger occupant detection system pressure sensor (G452) together with the wiring harness out through the opening in the seat pan. Then the passenger occupant detection system control module (J706) must be guided out through the opening.
Damage risk.
• Do not bend the seat occupied recognition pressure hose and mat.
- Remove the seat pan cover with upholstery with the seat occupied recognition mat - 2 -, the passenger occupant detection system pressure sensor and the passenger occupant detection system control module.
- Separate the cover from the seat pan upholstery. Refer to => [ Seat Cover and Cushion, Standard, Comfort and Folding ] Seat Cover and Cushion, Standard, Comfort and Folding.
Do not separate the seat pan cushion from the seat occupied recognition mat.
Installation
Do not disconnect the electrical connectors on the passenger occupant detection system pressure sensor and the passenger occupant detection system control module.
Installation is reverse of removal, but note the following:
• Follow all safety precautions when working with pyrotechnic components. On the passenger occupant detection system, refer to => [ Passenger Occupant Detection Sensor Precautions ] Passenger Occupant Detection Sensor Precautions.
• Before handling pyrotechnic components (for example, connecting electrical connector), the person handling them must discharge static electricity. For example, by briefly touching the door striker pin.
• Do not bend the seat occupied recognition pressure hose and mat.
• Make sure the connectors are installed all the way in and are secure.
Connect the battery with the ignition switched on. Pyrotechnic components could deploy after connecting the battery if they were not repaired correctly. Individuals must not be inside the vehicle when connecting the battery.
- Connect the battery ground cable with the ignition turned on.
When installing a new service kit and after each repair to the front passenger seat during which the seat and/or the backrest cover is disengaged, a basic setting procedure must be performed for the passenger occupant detection system control module. Refer to => [ Passenger Occupant Detection Sensor Precautions ] Passenger Occupant Detection Sensor Precautions.
- At the end, select the "Airbag" function in "Guided Fault Finding" using the Vehicle diagnostic tester.
